Hu, Helen H.; Creem, Sarah H.; Gooch, Amy A.; Thompson, William B. | Visual cues for perceiving distances from objects to surfaces (Abstract) | An accurate perception of the distance between an object and a nearby surface can increase a viewer?s sense of presence in an immersive environment, particularly when a user is performing actions that affect or are affected by this distance. Two experiments were conducted examining the effectiven... | Distance perception; immersive environment | 2002-02-03 |

Peay, Wayne J.; Hess, Stephen H.; Sharp, Edward M. | Utah education network: a collaborative model | High-speed data communications networks are transforming the operations, services, and roles of libraries. While the installation of the physical network is often the focus of activity, the administrative and political issues are, in fact, fundamental. For libraries to participate in and influence t... | Utah Education Network | 1994-10 |

Parker, Steven G.; Johnson, Christopher R. | Interactive manipulation of contour data using the layers program | The "layers" program is useful for visualizing and editing large sets of contour data. These datasets arise frequently when trying to extract geometry from MRI slices. Due to the imprecise nature of the MR imaging and segmentation processes, the contours extracted may not accurately reflect the huma... | Contour data; Layers program; MRI slices | 1994 |

Cotter, Neil E. | Prejudicial search and backprop | This paper introduces the combination of backward error propagation and prejudicial search. Prejudicial search is a method, which like simulated annealing, guarantees convergence to a global minimum as time approaches infinity. Unlike simulated annealing, its application is more flexible because it ... | 1991 | |

Sikorski, Kris | A note on optimal algorithms for fixed points | We present a constructive lemma that we believe will make possible the design of nearly optimal 0(dlog | ) cost algorithms for computing eresidual approximations to the fixed points of d-dimensional nonexpansive mappings with respect to the infinity norm. This lemma is a generalization of a two-... | Fixed points; Constructive lemma | 2009 |

Kniss, Joe; Ikits, Milan; Lefohn, Aaron; Hansen, Charles D. | Closed-form approximations to the volume rendering integral with Gaussian transfer functions | In direct volume rendering, transfer functions map data points to optical properties such as color and opacity. We have found transfer functions based on the Gaussian primitive to be particularly useful for multivariate volumes, because they are simple and rely on a limited number of free paramet... | Volume rendering | 2003-07-25 |

Industrial revolutions: from canal systems to computer networks | Today's so-called "Information Revolution" is often compared to past industrial revolutions, especially a British Industrial Revolution which took place between 1750 and 1830 and a Second Industrial Revolution which is believed to have occurred in the United States between 1880 and 1940. The compari... | Information technology; Information Age | 2000 | |

Breaderson, Dean J. | The I3Stick: an inexpensive, immersive, interaction device | Virtual environments require interaction devices that are intuitive and ergonomic, yet capable of many input parameters. Many devices satisfying these requirements can be expensive, difficult to manipulate, and often require the integration of large software libraries with existing applications. We ... | Virtual environments; I3Stick; Interaction devices | 1999 |

Henderson, Thomas C. | Reaction-diffusion processes as a computational paradigm | Turing introduced reaction diffusion systems (RD-systems) as a mechanism which made possible the differentiation of morphological structure. We have shown how these systems can be used to provide an information network for smart sensor systems. However, we propose here that reaction diffusion system... | Reaction diffusion systems; RD-systems; Computational paradigm | 2000 |

Henderson, Thomas C. | Utah range database | This document describes in detail the range database provided by the Department of Computer Science at the University of Utah. This document is intended for the person(s) involved in installing the database and those using the database. The images are in four sets: the University of Utah images, SR... | Utah range database | 1986 |

Lyche, Tom | A note on the Oslo algorithm | The Oslo algorithm is a recursive method for updating the B-spline representation of a curve or tensor product surface when extra knots are added. In the present note the derivation of this method is simplified. | Oslo algorithm; B-spline; Curve product surface; Tensor product surface | 1987 |

Boll, Steven F. | Improving linear prediction analysis of noisy speech by predictive noise cancellation | The analysis of speech using Linear Prediction is reformulated to account for the presence of acoustically added noise and a technique is presented for reducing its effect on parameter estimation. The method, called Predictive Noise Cancellation (PNC), modifies the noisy speech autocorrelations ... | Linear prediction; Predictive Noise Cancellation; Noisy speech; Sppech analysis | 1977 |

Brunvand, Erik L. | Speed without fear: composable self-timed GaAs circuits | We have designed a set of self-timed gallium arsenide building blocks that are suitable for composing into larger systems. Systems designed using these modules can be easier to design and modify than their globally clocked counterparts, while maintaining high performance.

Durney, Carl H. | A computer graphics method for solving transcendental equations | There are a number of ways to determine the values of x which satisfy the equation F(x)=0. (The case of interest here is that in which F i s a complex function of the complex variable x.) One way is to search for values of x which make Real (F(x)) and Imaginary (F(x)) both zero at the same time wher... | Transcendental equations | 1970 |

Keller, Robert M. | Semantics of networks containing indeterminate operators | We discuss a denotational semantics for networks containing indeterminate operators. Our approach is based on modelling a networks by the set of all its possible behaviors. Our notion of behavior is a sequence of computational actions. The primitive computational action is an event: the appearance o... | 1984 |
